Abstract (en)
[origin: EP4008840A1] An excavator 100 includes a lower traveling body 1, an upper turning body 3 turnably mounted on the lower traveling body 1, actuators configured to drive driven portions including the lower traveling body 1 and the upper turning body 3, a power storage device 19 mounted on the upper turning body 3 and used as an energy source for driving the actuators, a cooling circuit 60 configured to cool the power storage device 19, and a fan 90 mounted on the upper turning body 3 and configured to blow air to a radiator 62 and a condenser 82B for cooling the radiator 62 and the condenser 82B. Further, the power storage device 19 is arranged such that the power storage device is apart from a path in which air outside the upper turning body 3, by an operation of the fan 90, is introduced into inside the upper turning body 3, passes across the heat exchanging device, and is discharged to the outside of the upper turning body 3.
